Known issues on the 2015 MDX. Three recalls are on federal record for this model year: exterior lighting, where moisture entering the tailgate lid lights can cause a loss of the taillights and reduce the visibility of the vehicle to other drivers; a gasoline fuel pump failure that can stall the engine while driving; and a fuel tank assembly leak that can result in a fire in the presence of an ignition source. Owners have filed 97 complaints and 140 technical service bulletins have been issued for the year. This manual carries the factory diagnostic and repair procedures behind each of those systems.
From a scheduled service interval to a fuel-delivery diagnosis or a rear lighting circuit that keeps failing, it keeps you on the OEM procedure and the correct specification for your specific 2015 MDX.
